SEWING-MACHINE.

SPECIFICATION .forming part of Letters Patent No. 268,122, dated November 28, 188.0.

l Application led January 11, 1882. (No model.)

To all whom itmay concern:

.Be it known that l, CHARLES H. PALMER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements relating to Sewing-Machines, of which the following is a specification.

My experiments have been made with machines for sewing straw braid. The improved machine may be` used for various analogous classes of work where there is but little breadth of the material extending into the machine beyond the line of the seam. I will describe it as sewing straw braid.

The invention relates t0 the feeder and associated devices. The feeder may be of the ordinary form, except for a ledge or bearingsurface farther back in the machine. The

in the machine and the feeder acts thereon,

` compressing the same between itself and the the main shaft.

presser-foot, the action proceedsiu all respects in the ordinary manner; but when through' any contingency the machine works empty the teeth of the feeding device/are not allowed to come in contact with the presser-foot. The back surface referred to on the feeder at each lift of the feeder comes in contact with the back arm on the presser-foot and lifts it.

The following is a description of what I consider the best means of carrying out the invention.

rIhe accompanying drawings form a part of this specification.

Figure l is a side elevation, partly in section, showing all the novel parts, with so much of the ordinary parts as is necessary to indicate their relation thereto. Fig. 2 is a front view of the same. Fig. 3 represents a detail, being a plan View of the presser-foot.

Similar letters of reference indicate corresponding parts in all the figures. The parts not shown may be of any` ordinary or suitable construction.

A is the framing; A', the workplate; B,

B3 is a crank thereon engaging the feeder.

G is the presser-bar, urged downward by a spring, (not shown,) in any ordinary or suitable manner.

and little liability of derangement.

Gr is the presser-foot.

G2 is an arm or backward extension from the presser-foot, which performs an important function.

H is the feeder. It is what is known as the four-motion feed,77 actuated by the eccentric or crank B3 on the shaft B, before referred to. The feed is gaged in any ordinary or suitable manner. The toothed portion, which rises through a suitable orifice in the work-plate A', and is effective in acting on the work, is marked H. An arm or extension reaching upward at a point farther in the rear (marked H2) is smooth. 'Its height is carefully adjusted, so that it will come in contact with the part Gr2 of the presser-foot and hold it just clear ot' the teeth H when the machine is working idly, without any fabric under the presserfoot, but will not touch the part G2 and will be f no effect when there is braid in the machine, because the teeth H will lift the presser-foot through the medium ot' the braid. The back extension, H2, of the feeder may he made in one with the front portion, H', and with the main body H, and someof the benefits of the invention will be thereby obtained 5 but I make it in a separatepiece, secured adjustably to the part H by the screw P, standing in a vertical slot in the part H', as shown. I thus provide for adjusting the height of the two parts, H' H2, relatively to each other. This may become desirable to allow for the difference of wear of the teeth H' and the back extension, H2.

My improved machine involves little spring The parts may be very light. The inertia is little and the vibration slight.

Most of the ordinary attachments and applianccs used in sewing-machines may be used with this invention.

This application is a division of an application for Letters Patent for sewing-machines filed in United States Pat-ent Office by me August 12, 1880, Serial No. 15,250.

I claim as my inventionl. In a sewing-machine, the device H2, rising and sinking with the feed, in combination therewith, and arranged to strike the-presser-foot or a part connected thereto, so as to raise it out of contact with the feed at each rise of the lai:-
